Product Introduction

EN10216 1.4410 Seamless Pipe is a duplex stainless steel consisting of an alloy of chromium, molybdenum and nickel-nitrogen. It has high strength, good impact toughness and good overall and local resistance to strong corrosion. Our pipes are seamless tubes made by hot-rolling and cold-drawing processes with smooth inner walls. It is available in a wide range of sizes and can be freely selected. It can also be customised by contacting us. Due to its superior performance, EN10216 1.4410 Seamless Pipe is widely used in power plants, shipbuilding, aviation and other fields.

Compared to 316L and 317L austenitic stainless steels, EN10216 1.4410 Seamless Pipe has superior resistance to pitting and gap corrosion. It has a lower coefficient of thermal expansion and higher thermal conductivity than austenitic. It also has twice the compressive strength of austenitic and is lighter in weight, making it less costly.
